Some of the players in the club uses the graphical format below to receive their opponents' moves. Others use plain text messages, others use PGN.

This page is for those who use the html message format, instead of
plain text and PGN. (These settings can be changed anytime by the
players).
For players using the html format, the server generates the changed
game diagram after each move in html format.
Using an html compliant email client or web service is necessary to use
this feature. All the modern email clients support displaying standard
html messages.
Players who use an email client that doesn't support html message
format won't be able to use this feature. They receive their opponents'
moves, or whole games in plain text or in PGN format instead of the
graphical boards. They may need a different software to display the
boards. For example ECTool is a right software for them.

Players can choose which piece set they want to use in their graphical
boards generated by the chess server.

In competitive chess, a player scores one point for a win, a half-point for a draw, and zero points for a loss. So the rankings at the end of a tournament are easy to calculate by simple addition.

In the early 19th century, when modern competitive play began, draws were ignored, and a match was won by the player who first scored an agreed number of wins, or who had the most wins after an agreed number of games. With the advent of all-play-all tournaments (the first international all-play-all was held in London in 1851) draws became more important. At first, rules were devised to discourage draws, which were very unpopular with the chess public, but gradually these were dropped and draws were counted as a half-point.

If we want to play a game with somebody but don't want it to change our results, the challenge should be sent for a friendly game.
It's useful if we want to analyze a setup, replay a game, or even only for practicing.
This can be combined well with starting games from predefined setups.
